i read it in a tuning magazine a while back im sure its very general, i remember when i first put on my intake and exhaust i equated the difference to being able to accelerate with a passenger like it used to with only me, going by the 10-1 formula the mods would yield about 17 hp which i agree is a bit high.. im going to go out on a limb and say that if those mods (maybe 10hp) make it feel 170lbs lighter, than 10lb equals closer to .6 hp
